Celestron CGEM-DX 1100 11\" Schmidt-Cassegrain Telescope

This item is priced in Canadian dollars.

Celestron commitment to providing the best value and quality amateur telescopes continues with the CGEM-DX series computerized telescope.

Celestron's legendary 11" Schmidt-Cassegrain telescopes with XLT coatings have been coupled to the new CGEM-DX mount to deliver one of the most affordable 11" Catadioptric telescopes on the market today.

The CGEM-DX mount delivers improved tracking, using high-quality gears, drives and bearings, permanent periodic error correction, and tracks well past the meridian (the best part of the sky).

The deluxe heavy-duty tripod coupled with the CGEM-DX mount is suitable to carry their 11" optical tube assembly. The maximum payload is 50lbs. The mount can slew the 11" telescope around at 5° per second. That translates to less waiting, and more observing.

Catadioptric telescopes boast flexible photographic options, such as prime-focus, eyepiece projection, focal reducers/field flatteners, and piggyback mounts.

Celestron is known for innovation, and they continue this tradition with the new "All-Star" polar alignment that does away with the polar finder.

  • Start with a rough polar alignment
  • Perform a two-star alignment and add one calibration star
  • Select "Align Mount"
  • Locate and centre a bright star, preferably high up near the meridian, away from the Zenith, Celestial Pole or E/W horizon
  • Locate the same star in the database
  • Centre the star in a reticule eyepiece, using the mounts azimuth and latitude adjustments
  • Update the computer star alignment
